Answer:
➡️ Work done = 2450 joule
➡️ Power = 612.5 watt
Step-by-step explanation:
Work done = energy
Energy = potential energy in this case.
PE = mgh
m = mass, g = acc due to gravity, h= height
P. E. = 50 ☓ 9.8 ☓ 5
P.E. = 50 ☓ 49
P.E. = 2450 joules.
Power = energy / time
Power = 2450/4
Power = 612.5 watt
